Kubernetes, Loadbalancing, and Nginx Ingress - AKS - kubernetes

Question

NGINX Ingress Controller - https://github.com/kubernetes/ingress-nginx
AKS Loadbalancer
Docker containers
My goal is to create a K8s cluster that will allow me to use multiple pods, under a single IP, to create a microservice architecture. After working with tons of tutorials and documentation, I'm not having any luck with my endgoal. I got to the point of being able to access a single deployment using the Loadbalancer, but introducing the ingress has not been successful so far. The services are separated into their respective files for readability and ease of control.
Additionally, the Ingress Controller was added to my cluster as described in the installation instructions using: kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.35.0/deploy/static/provider/cloud/deploy.yaml
LoadBalancer.yml:
apiVersion: v1
kind: Service
metadata:
name: backend
spec:
loadBalancerIP: x.x.x.x
selector:
app: ingress-service
tier: backend
ports:
- name: "default"
port: 80
targetPort: 80
type: LoadBalancer
IngressService.yml:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
spec:
rules:
- http:
paths:
- path: /api
backend:
serviceName: api-service
servicePort: 80
api-deployment.yml
apiVersion: v1
kind: Service
metadata:
name: api-service
spec:
selector:
app: api
ports:
- port: 80
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: api-deployment
spec:
selector:
matchLabels:
app: api
tier: backend
track: stable
replicas: 1
template:
metadata:
labels:
app: api
tier: backend
track: stable
spec:
containers:
- name: api
image: image:tag
ports:
- containerPort: 80
imagePullPolicy: Always
imagePullSecrets:
- name: SECRET
The API in the image is exposed on port 80 correctly.
After applying each of the above yml services and deployments, I attempt a web request to one of the api resources via the LoadBalancer's IP and receive only a timeout on my requests.

Found my answer after hunting around enough. Basically, the problem was that the Ingress Controller has a Load Balancer built into the yaml, as mentioned in comments above. However, the selector for that LoadBalancer requires marking your Ingress service as part of the class. Then that Ingress service points to each of the services attached to your pods. I also had to make a small modification to allow using a static IP in the provided load balancer.
